Hi there, I found this ideabook on Houzz about different eco-friendly sinks, and there's a mention of copper sinks in it. It sounds like they could be a great option if pre-aged, since copper has anti-microbial properties: https://www.houzz.com/magazine/green-and-clean-ecofriendly-bathroom-sinks-stsetivw-vs~2951379

I myself don't have any personal experience with them except that I think copper kitchen sinks are gorgeous!!

Hi Angel Coburn_Tucker,

If you choose copper, you'll find it is amazingly easy to maintain! Hammered copper is particularly simple since it doesn't show fingerprints as stainless steel or shiny copper does. For basic cleaning simply use a mild soap and warm water. Keep your copper product clean and dry by wiping it down after each use with a soft cloth. Harsh abrasives or copper cleaners should never be used on our products as they may affect the finish. For extra protection, a product such as Flitz Faucet Wax+ may be applied.

For more information specific to finish types, please visit our website: http://www.nativetrails.net/cm/downloads/care_maintenance.html

Hope that helps.
